Dear all, what code should I write in order to extract the file name from a give path? Let's say that I want to get the file "my file.xls" which is in the directory/folder "My documents"; since I work both with Windows and Linux, the paths I am looking at are in the format:
path.windows<-"\\home$\\lm667\\My Documents\\my file.xls" path.linux<-"/home/My Documents/my file.xls" I used two words for the file name because sometimes the file names have multiple words rather than a single one separated by capitals, "." or "_". The code should now get the file name, which is included between "\\" (or "/") and ".xls" but I don't know what regular expression will do the trick. Once the file name has been assigned to a vector, it should be easy to remove it from the path.windows/.linux and obtain a vector with the path on its own. Essentially the output should be as follows: > file.name [1] "my file.xls" > path.w [1] "\\home$\\lm667\\My Documents\\" > path.l [1] "/home/My Documents/" Thank you, Luigi ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
